clear, and exact description.

One obJect of the invention is to provide a new and improved stand, more especially I designed for use in boiler shops and other places for supporting a hydrocarbon burner or other burner, and arranged to safely hold the burner and to allow vertical and horizontal adjustment for effectively and accurately directing the flame ofthe burner to the work to be heated.

.Another object is to permit of conveniently wheeling the stand about from one place to another so as to bring the burner within convenient reach of the work.

In order to accomplish the desired result, use is made of a supporting member having holding means adapted to removably hold the supply pipes of the burner to support the latter in position on the said supporting member, a head on which the said supporting member is mounted to swing in a vertical plane to hold the burner in a horizontal or inclined position, and .a post on which the said head is mounted to turn in a horizontal plane.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in alt the views; Figure 1 is an edge view of the stand with. a burner in position thereon; Fig. 2 is a side elevation of the same with parts of the base in section; Fig. .3 is an enlarged cross section of the stand on the line 33 of Fig.

Fig. 10 is a sectional side elevation of the modified form of burner shown in Figs. 7 8 and 9, and with the supporting member in inclined position; Fig. llis a cross section of a modified form of the supporting member, head and stand; and Fig. 12 is a face view of the same.

The stand illustrated in Figs. 1 to 6 is mounted on a suitable base 10 provided with a vertically. disposed .segment 11 on which is pivoted at 12 the lower end of a post 13 to permit of swinging this post from vertical into inclined position either to the right or to the left. The post 13 is locked in adjusted position to the segment 11 by the use of a locking slide 14 mounted to slide on a bolt 15 held on the post 13, and the slide 14 is controlled by a hand lever 16 fulcrumed on the post 13. A spring 17 presses the slide 14. downward so as tohold the lower end thereof in engagement with the teeth 18 of the segment 11, thus locking the post 13 against swinging movement. On thepost 13 is mounted to slide up and-down the hub '20 of a bearing 21, preferably in the form of a disk, as plainly shown in Fig. 5, and on the hub 20 is mounted a locking pin 22 adapted to engage a toothed side 23 of the post 13 to lock the bearing 21 in the adjusted position on the post 13. Aspring 24: presses the looking pin 22 to normally hold the same in engagement with the toothed side 23 of the post 18, The bearing 21 fits into an annular recess formed in a horizontal extension 31 .of a vertically disposed head 32 on which is mounted to turn a supporting member in the form of a disk, against theface of which are held the supply pipes 50 and 51 of a burner 52 of usual construction. The supply pipes 50 and 51 are held against the face of the supporting member 40 by the use of an arm 60 provided at its inner face with recesses 61, 62 fittingover the pipes 50 and 51. The lower end of the arm 60f is fulcrumed on a pin 63 held on lugs 4L5 projecting from the face of the supporting member 10. A spring 64 is attached to the arm 60 and bears against one of the lugs so as to normally hold the arm 60 in closed position against the face of the supporting member 40 to properly support the supply pipes and 51. When it is desired to remove the burner it is only necessary for the operator to swing the arm forwardly to allow of lifting the pipes 50 and 51 out of the recesses 61, 62v

The extension 31 of the head 32 is mounted to turn on the bearing 21 and islocked thereto after a desired position has been reached by a locking pin 33 engaging one of a series of apertures 26 formed in the top of the bearing 21 (see Figs. 3 and 5). The locking pin 33 is pressed on by a spring 34 to normally hold the pin 33 in engagement with one of the apertures 26. A similar locking pin 43 is used for locking the supporting member 40in position on the head 32, the said pin 43 being mounted to slide on the supporting member 40 and being adapted to engage one of a series of apertures 35 formed in the rim 36 of the head 32. A spring 44 presses thep'in, 43 to hold the latter in en- .gagement with one of the apertures 35.

From the foregoing it will be seen that by the arrangement described the bearing 21 with the head 32 supporting the member- 40 and the burner 52 can be readily raised or lowered on the post 13 and locked in the adjusted position. In a like manner the head 32 can be turned in a horizontal plane on the bearing 21 and locked in the adjusted position by the pin 33, and the said member 40 can be turned in a vertical plane in the head 32 and locked in the adjusted position by the pin 43. Thus by the arrangement described the burner 52 can be readily moved into any desired position for effectively and actively directing the flame of the burner to the work to be heated at the time. The downward sliding movement of the hub 20 of the bearing 21 is limited by a stop pin 27 held on the post 13. In order to permit of conveniently wheeling the stand about from one place to another, the following arrangement is made: To the lower end of the post 13 are secured angular axles 70 provided with Wheels 71 normally standing above the floor on which rests the base 10. The wheels 71 extend with their lower portions into openings 72 formed in the base 10, and when the post 13 is swung from the vertical position shown in Figs. 1 and 2 to the right into the inclined posit-ion indicated in Fig. 6 then the Wheels 71 move into engagement with the fioor and raise the base 10 off the floor thus allowing wheeling of the stand from one place to another.

In the modified form shown in Figs. 7,

I 8, 9 and 10, use is made of a base 100 on which is secured a segment 101 provided near its peripheral edge with apertures 102 adapted to be engaged by a pin 103 extending transversely through a post 104 fulcrumed at 105 on the segment 101. On the post 104 is held vertically adjustably a bearing 106 by the use of a set screw 107, and on the top of the bearing 106 rests a head 108 through which extends the post 104 to allow the head to turn in a horizontal plane. The head 108 is provided with a transverse pivot 109 extending through slots 110 formed in depending lugs 111 of the supporting member 112 provided with an elongated slot 113 for the passage of the post 104. The supporting member 112 is adapted to support the supply pipes 120, 121 of the burner 122, and the said supply pipes are clamped to the forward end of the supporting member 112 by a clamping bar 130 engaged by a bolt 131 held on the supporting member 112. The rear end of the supporting member 112 is provided with a loop 115 through which extends the rear ends of the supply pipes 120, 121. From the' foregoing it will be seen that by the arrangement described the head 108 is mounted to turn in a horizontal plane and the supporting member 112 is adapted to turn in a vertical plane, and when the desired adjustment is reached the supporting member 112 is fastened in place by a bandled nut 116 screwing on one outer end of the pivot 109, as will be readily understood by reference to Figs. 7 and 8.

In the modified form shown in Figs. 11 and 12, the supporting member 140 is provided on top with a hook bolt 141 for engaging the uppermost supply pipe 150 which with the lowermost supply pipe 151 is adapted to rest against the face of the supporting member 140. The supporting member 140 is provided with a rearwardly extending hub 142 mounted to turn on a horizontally disposed bearing 143 formed on a head 144 provided with a hub 145 slidingly engaging the post 146 to which the hub 145 is adjustably secured by a set screw 147. The head 144 is provided with apertures 148 any one of which is adapted to be engaged by a spring-pressed pin 149 carried by the supporting member 140 to lock the latter in adjustment has been made. The hub 142 of the supporting member 140 is provided with bolts 160 engaging an annular groove 161 formed'in the bearing 143 to hold the supporting member 140 against. displacementon' the bearing 143 to allow turning of the supporting member140 on the said hub. It is understood that on loosening the set screw 147 the head 144 can be swung around on the post 146 and also moved up and down on the post to av desired position and then fastened in place by the set screw 147 In a like manner the supporting member 140 with the burner thereon can be turhed on the bearing 143 of the head 144 after the pin 149 has been withdrawn, and whenthe desired position is reached the pin 149 is engaged with a corresponding aperture 148.

Thus in either of the forms mentioned the burner can be conveniently and accurately adjusted to effectively direct the flame to the work in hand at the time.
